What kind of care is needed if small blemishes repeatedly appear in similar locations on the cheeks?

I am wondering what causes I should consider if small blemishes repeatedly appear in similar locations around the cheeks.

Even if I don't get a lot of acne all over my face, if small bumps or red blemishes keep appearing in the same areas, I worry that sebum might be continuously accumulating inside my pores.

I think a similar phenomenon could occur if your skin is irritated or if the products you use do not suit you.

I am wondering if I need to do any special care while the breakout subsides, or if it would be a good idea to consult a dermatologist to identify the recurring cause. I am being cautious because touching or removing them with my hands could leave red marks.

In this case, I would like to know if I need to visit while the breakout is actually active, or if I can receive a consultation even after it has subsided.

If I receive acne skin care, is it possible to receive treatments aimed at reducing the recurrence of similar problems, rather than just clearing up the immediate breakouts?

I would like to start by reviewing my lifestyle habits and how I use cosmetics, and receiving skin care only when necessary.
